One year after devastating wildfires tore through Los Angeles’ hillside communities, recovery has entered a new phase. Debris has largely been cleared. Permits are moving forward. Architects are drawing plans and many homeowners are finally preparing to rebuild.
But across fire-damaged neighborhoods, a difficult reality is slowing that progress: before homes can rise again, the ground beneath them often must be rebuilt first.
As recovery shifts from emergency response to long-term reconstruction, unstable soils, weakened slopes and fire-altered geology are significant barriers to getting families back home. These challenges don’t make headlines, but they are reshaping timelines, budgets and in some cases, whether rebuilding is even possible.
Before the Blueprint, the Groundwork
In hillside areas like Pacific Palisades, rebuilding does not begin with design plans or permits. It begins with determining whether the land itself can safely support a new structure.
Many of these neighborhoods were developed decades ago, before modern geotechnical standards and building codes were in place. Homes were often built on artificial fill or marginal slopes that met the standards of their time but would not meet today’s requirements. Wildfire adds a new layer of risk. Intense heat can alter soil composition, destroy root systems that stabilize hillsides, and leave slopes more vulnerable to erosion and movement during winter storms.
Now, as homeowners begin pre-construction investigations, they are discovering that rebuilding may require extensive site stabilization: soil replacement, deepened foundations, engineered grading, caissons drilled into bedrock or other structural reinforcement. These measures are highly technical, time-consuming and expensive—and they are often the first major hurdle in the rebuilding process.
Without addressing these conditions, homeowners may face long-term risks such as landslides, foundation failure or storm-related damage. Safe rebuilding requires understanding the site’s geology and, in many cases, stabilizing it before construction can begin.
Insurance Falls Short of Real-World Costs
Many families assumed that once cleanup was complete, rebuilding would be a straightforward process covered largely by insurance. A year later, as projects move into the engineering and pre-construction phase, they are discovering that the financial reality is far more complex.
Standard fire insurance policies often cover roughly $400 to $500 per square foot to rebuild a home. Yet the cost of constructing to modern California codes can range from $700 to $1,000 per square foot. That gap alone is significant, and it does not include geotechnical work.
Site stabilization can involve deep excavation, soil re-compaction, retaining systems or friction piles and caissons, which are reinforced concrete elements drilled into bedrock to anchor a structure. These systems are expensive, sometimes costing thousands of dollars per linear foot, and dozens may be required. It is not unusual for geotechnical improvements to add hundreds of thousands of dollars to a project before vertical construction even begins.
For some homeowners, these newly uncovered costs are creating difficult decisions: scale back, take on substantial additional debt or reconsider rebuilding altogether.
Safety Must Lead, Even When Time Matters
A year after the fires, there is understandable pressure to rebuild quickly. Families want to return. Communities want to recover. But rebuilding in fire-impacted zones requires a careful reassessment of whether the land can safely support new construction under today’s environmental and seismic realities.
Homeowners often ask, “My house was there for decades. Why can’t I just replace it as it was?” The answer lies in what we have learned. Updated seismic research, improved geotechnical science and evolving building codes reflect a better understanding of how and why structures fail. These requirements are intended not only to protect individual homes, but also neighboring properties and public safety.
Still, this creates a tension between modern safety standards and financial feasibility. Policymakers may need to explore ways to help homeowners bridge this gap—whether through targeted funding, technical assistance or carefully considered flexibility for rebuilding existing homes, similar to how historic renovations sometimes balance preservation with code compliance.
These are not easy decisions. But ignoring site conditions in the rush to rebuild could lead to greater risks and greater losses in the future.
Rebuilding Homes Starts With Stabilizing the Land
Architects today are not just designers. They are technical collaborators working alongside soil engineers and structural experts to determine what is feasible, what is safe and what is financially realistic for each site.
One year later, Los Angeles has made meaningful progress. Streets have been cleared, plans are taking shape and the will to rebuild is strong. Ensuring that recovery lasts will mean starting with the land itself—a step that may be complex and time-consuming, but one that lays the groundwork for safer, more resilient communities in the years ahead.
